Resumos

O estudo de plantas de feijão (Phaseolus vulgaris L.) submetidas à deficiência hídrica e temperaturas de 35-40º C umidade relativa (UR) 40-100%; 5-10ºC, UR 20-30%; 2-5ºC, UR 10-20%, realizado em casa de vegetação e câmara de crescimento, no Instituto Agronômico, em 1982, mostrou haver correlação negativa entre o acúmulo de prolina e o potencial de pressão de água nas folhas (psip). Os cultivares Curitibano e P-511, este último considerado resistente à seca e baixa temperatura, apresentaram o menor acumulo de prolina e o maior psip, confirmando a hipótese de que é possível o reconhecimento de material geneticamente resistente à escassez de água através da seleção de plantas que acumulam menor quantidade de prolina.

Four experiments were performed in growth chamber and greenhouse at Campinas, in 1982, to study the relations of dry bean cultivars submmited to period of water and temperatura stress. Adaptation of planta to stress conditions was measured through prolina accumulation and water potential (psip) in leaves. In all tested cultivars prolina content showed a straight negative correlation with water potential in leaves. Cultivars P-511 and Curitibano showed lower prolina content and higher water potential than the other under study, this confirming the hypothesis that it is possible to identify materiais genetically resistant to water stress by selection of plants or lines with low prolina content.

RESUMO

O estudo de plantas de feijão (Phaseolus vulgaris L.) submetidas à deficiência hídrica e temperaturas de 35-40º C umidade relativa (UR) 40-100%; 5-10ºC, UR 20-30%; 2-5ºC, UR 10-20%, realizado em casa de vegetação e câmara de crescimento, no Instituto Agronômico, em 1982, mostrou haver correlação negativa entre o acúmulo de prolina e o potencial de pressão de água nas folhas (yp). Os cultivares Curitibano e P-511, este último considerado resistente à seca e baixa temperatura, apresentaram o menor acumulo de prolina e o maior yp, confirmando a hipótese de que é possível o reconhecimento de material geneticamente resistente à escassez de água através da seleção de plantas que acumulam menor quantidade de prolina.

Termos de indexação: temperatura: água e umidade; prolina, potencial de água.

SUMMARY

Four experiments were performed in growth chamber and greenhouse at Campinas, in 1982, to study the relations of dry bean cultivars submmited to period of water and temperatura stress. Adaptation of planta to stress conditions was measured through prolina accumulation and water potential (yp) in leaves. In all tested cultivars prolina content showed a straight negative correlation with water potential in leaves. Cultivars P-511 and Curitibano showed lower prolina content and higher water potential than the other under study, this confirming the hypothesis that it is possible to identify materiais genetically resistant to water stress by selection of plants or lines with low prolina content.

Index terms: temperature, water and humidity; prolina; water potential.
